Product Information
Expansion tanks and related hardware allow coolant a place to expand and contract while it cools down. Expansion tanks are exposed to high pressure and constant heating or cooling cycles which oftentimes leads to pressure cracks in the plastic. Prevent your vehicle from leaking coolant and leaving you on the side of the road, and replace your vehicle’s expansion tank with this Mahle Behr part.
Engine Coolant Reservoir
The engine coolant reservoir, also known as an ‘overflow bottle’ is a crucial component of modern vehicle cooling systems. Its job is to capture the increased volume of engine coolant that is created as the coolant is heated and expands. It needs someplace to go, so a coolant line that typically runs from the radiator outlet to the top of the engine coolant reservoir will feed the reservoir, while the reservoir feeds the engine as it needs more coolant to send through the engine and back through the radiator.
Engine coolant reservoirs are typically made of plastic and can be either clear or opaque. Some performance or aftermarket overflow bottles are made of aluminum or other more durable materials.
